APPARATUS FOR WATERING CATTLE.

i Specication of Letters Patent No. 8,479, dated October 28, 1851.

Be it known that I, S. W. VooD, of Rochester, in the county of Monroe'and State of New York, have invented a new and useful Improvement inOattle-Pumps; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawings, making a part thereof, in whichy Figure lrepresents a perspective view and Fig. 2 represents a section throughthe line -m of Fig. l.

Similar letters in the several figures represent the same parts.

The nature of my invention consists in the arrangement of a coggedsleeve on the shaft of the main or upper carrying pulley, between whichand a stationary collar secured to the shaft, on which the sleeve moves,is arranged a spiral spring which gradually stops the running back ofthe buckets, without any sudden jar, and when the cattle step upon theplatform, the spiral spring forces the sleeve up to the thread upon theshaft, which insures their instantaneous action; and so that by its ownaction the endless chain of b uckets will run back suiiciently far inthe pump cylinder to prevent its freezing, and then ungear itself, thussaving the necessity of running the endless chain backward during theraising of the platform which by the weight of the cattle upon it putsthe pump in motion.

To make others skilled in the art to make and use my invention I willproceed to describe the same with reference to the drawin s.

gOn a shaft (A) which has its journals resting in a frame suitablyprepared for that purpose, is secured the cog wheel (B) and on a drumpulley or other enlarged part of said shaft is wound a band, or cord,one end of which is fastened to the front of the vibrating platform (C)and to the other end is secured a weight (D) which will be suflicient toraise said platform. The cog wheel meshes into a cogged sleeve (E)arranged onthe stationary shaft (F) and on said shaft is also placed themain carrying pulley (G) over which the endless chain of buckets passes.At the bottom of the'well spring or other place from which the water isto be drawn, is also arranged a carrying pulley (H) over which theendless chain of buckets passes and thence into the pump cylinder (I).

On the inner side of the cogged sleeve (E) is cut a. female screw whichwhen the motion of the buckets is reversed by the raising of theplatform, catches into a thread cut upon the shaft and runs said sleevefar enough back on said shaft, to throw out of gear the stops (f, f) oneof which is on the end of said sleeve--the other on the hub of the maincarrying pulley And when any weight comes upon' the platform sufficientto set the pump in motion the sleeve is immediately run forward again bythe before described thread and screw until the stops or cams catch ineach other, and sets the carrying pulley and endless chain of bucket-sin motion. A spiral spring (r) is placed between the end of the sleeve(E) and a collar on the shaft for the purpose of starting up said sleeveso that the screw may carry it into gear without any slipping when thecattle step upon the platform, and which as the sleeve runs back, iscompressed gradually by it, and as gradually checks the running back ofthe buckets which carry back the excess of water out of the stock orpipe. By increasing or diminishing the length of the cams and the threadof the screws, the buckets may be run back more or less into the pumpcylinder as may be desired.

The buckets (z) are made of gum-elastic gutta-percha, or other elasticmaterial formed into a sphere, and may be cast upon links, having eyestherein for connecting them into an endless chain, or may be cast uponthe chain already formed, by first putting it into a fluid state bydissolving it. The spherical shape of the buckets allow them to passover any inequalities in the pump cylinder, and the elasticity of thematerial of which they are formed, allows them to work so closelyagainst the innerperiphery of the cylinder as to form a vacuum behindtheininto which the water will rise, thus making them act as suction andlifting buckets.

The operation is as follows: When the platform is raised by means of theweight winding up the cord which is attached to it, any weight comingupon said platform, will cause it to sink which by the unwinding of thecord will put the cog-wheel in motion, and this in turn will start thecogged sleeve and which in turning is run forward by the thread on saidsleeve and the screw on the stationary shaft until the stop or cams comein Contact. and rotates the main carrying pulley which turns also onsaid stationary shaft and sets the endless chain of buckets in motion.When the cattle leave the platform7 it is raised immediately by theWeight attached to the end of the cord which passes around the shaft asbefore described.

Having thus fully described my invention What I claim therein as new anddesire to sec-ure by Letters Patent is,

In combination With a pump Worked by an 15 endless chain of elasticballs and operated running the sleeve into gear when the cattle 20 stepupon the platform, and for gradually stopping the platformas it rises,and the buckets as they run back into the stock or pipes for the purposeof carrying back the v'vater as herein fully described and repre- 25sented.
